23_15/2011Metal Oxide Particles: Multi Ball-In-Ball Hybrid Metal Oxides (Adv. Mater. 15/2011)

A strategy for the synthesis of composition-tunable hybrid metal oxide particles with a unique ball-within-ball structure is reported on p. 1720 by Moonhyun Oh and co-workers. The systems were logically formulated using the following processes: 1) CPP preparation using a precipitation method, 2) cation exchange reaction for composition transformation of CPPs, and 3) a final calcination processing of prepared CPPs that engenders decomposition of the CPPs and formation of metal oxides.
